7,8-dihydro-8-oxoguanine

10/03/2022 - "This work shows that patients with CRC not only have an increased level of 8-oG and that the studied polymorphisms modulate risk of cancer, but also indicate a relationship between these 2 phenomena, which may contribute to a better understanding of the mechanism of neoplastic process in case of reduced effectiveness of DNA repair mechanisms. "
08/28/2020 - "In pancreatic Panc-1 cancer cells, an increase of oxidative stress enhances the level of 7,8-dihydro-8-oxoguanine (8OG) more in the KRAS promoter region containing G4 motifs than in non-G4 motif G-rich genomic regions. "
10/05/2010 - "Continuous oxidative damage inflicted on DNA produces 7,8-dihydro-8-oxoguanine (8-oxoG), a commonly occurring lesion that can potentially cause cancer by producing G → T transversions during DNA replication. "
06/01/2007 - "Basal levels of endogenously generated oxidative DNA modifications such as 7,8-dihydro-8-oxoguanine (8-oxoG) are present in apparently all mammalian cells, but their relevance for the generation of spontaneous cancers remains to be established. "
01/01/2018 - "Here, we disrupt the peroxiredoxin 1 (PRDX1) and 7,8-dihydro-8-oxoguanine triphosphatase (MTH1) genes in cancer cells and demonstrate that PRDX1 and MTH1 cooperate to prevent accumulation of oxidized guanine in the genome. "

01/01/2007 - "7,8-Dihydro-8-oxoguanine (8-oxoG) is a well-known oxidative lesion in DNA and is related to carcinogenesis and ageing processes. "
10/03/2006 - "The modified guanine, 7,8-dihydro-8-oxoguanine (also known as 8-hydroxyguanine) is one of the major oxidized bases generated in DNA by reactive oxygen species and has gained most of the attention in recent years as a marker of oxidative DNA injury and its suspected role in the initiation of carcinogenesis. "

04/13/2001 - "The induced atherosclerotic plaques showed elevated levels of the DNA damage marker 7,8-dihydro-8-oxoguanine (8-oxoG) as demonstrated by immunohistochemistry. "

01/01/2019 - "Nevertheless, the development of lung pathology, including asthma, chronic obstructive pulmonary disease, and ozone-induced lung injury, is associated with oxidant stress; as evidence, there is a significant increase in levels of the modified guanine base 7,8-dihydro-8-oxoguanine (8-oxoG) in the genome.
